SPECIFICATION forming part of Letters Patent N0. 283,703, dated August21, 1883.

Application filed, April 28, 1883. (No model.)

To all whom it may concern.-

Be it known that I, TIBERus DOUGHERTY, a citizen of the United States,residing in the city and county of Philadelphia, State' of drawings, in'which- Figure l is a partial side elevation and partial vertical sectionof an excavating apparatus Fig. 2 is a rear view thereof. Fig. 3 is ahorizontal section inline :n a', Fig. 2. Fig 4 is a view of a detachedportion, partly sectional. Fig. 5 is a section of a portion thereof inline y y, Fig. 4. Fig. Gis a bottom view of thebucket of the apparatus.Figs. 7, 8, and 9 are views of detached parts of the frame and thefastenings thereof, enlarged, and portions thereof in section. f

Similar letters of reference indicate corresponding parts in the severalfigures.

My invention consists of an apparatus for excavating or cleaning wellsor eesspools, the same being strong and durable, reliable in operation,and easily set up and taken down, as will be hereinafter fully setforth.

Referring to the drawings, 'A represents an upright frame, which'isformed 'in sections, whereby it may be lengthened or shortened, asdesired.

B represents a bucket or conveyer, which is guided on the frame A, andhas connected with it an operating chain or rope, C, which is passedaround sprocket wheels or pulleys D D at the top and bottom of theframe,

whereby the bucket may be raised and lowered, the shaft of the toppulley, D, carrying sprocketwheels or pulleys a., which, by means ofchains or belts and other suitable wheels or pulleys, e', and gearing,may be readily rotated, so as to impart motion to the rope C, eithershaft of the gearing being adapted for attachment of a crank-handle orhand-wheel.

The pulley DYis Vinclosed by a casing, D", which guards said pulley andprevents entrance of matter or dirt thereto without interfering with thepassage of the rope C, said 5o casing being loosely tted on the shaft ofthe pulley D', andretained in position by means of a bolt, Y), which ispassed through a round, o, at the bottom of the frame A, and secured bya nut, b.

The bucket is formed of two parts hinged together above the center, soas to open below. The back part is dat, and the front part is somewhatof mold-board shape from the center to each side and toward the bottom,thus leaving at the center a peak, E, the bottom of which is sharp, andthe sides taper toward the bottom, making a sharp bottom for the bucket,it being noticed that the peak extends at a right angle to the bottomedge of the buck.- et, and said edge is parallel with the frame A.

The sides of the back part of the bucket have pivoted to them, as at ox,elbow-levers F, the lower ends whereof are connected ata different pointto the sides of the front part, as at cx ax, and the upper ends havelaterallyprojecting gudgeons d., whichare adapted to enter vcurved slotse, formed in projecting arms G, which are secured to the uppaer part ofthe frame A, the slots begimiing at the bottoms of said arms and curvingupwardly and inwardly, whereby, when the gudgeons enter said arms, theyare drawn rearward or inward, and

cause the elbow-levers to throw out the front l part of the bucket, thusopening the bottom of the latter. ln the present case each lever F andtheU adjacent sides of the two parts of the bucket'have a common pivot.

In order to remove the bucket, I form in vastly strengthens said pieces,and are also connected at intervals by rounds or crosspieces,

thus producing a strong structure.

K represents a cross-head, whose ends are bifurcated to straddle and beremovably connected with the top of the frame A, and has in its center athreaded opening for the engagement of a screw, L, which is formed withan operating wheel or handle, L', and has f1tted to it at its upper enda nut, M, which is preferably formed with upwardly-extending wings, thepoints whereof are adapted to take IOO firm hold of the ceiling of theprivy or outhouse to. be cleansed, the operation of the screw Lcausing'the nut'to tighten against the ceil- .l

(ing, and, owing to the downward pressure of 5 the cross-head,occasioned by the screw and resistance offered by the ceiling, the framewill be firmly held in position. The screw L4 is right-and-leftthreaded, one party entering the cross-head or bridge K and the otherpart entering the pointed nut M. The wheel or handle L is rigidlyconnected with the screw,l andwhen said screw is rotated it moves thebridge and nut powerfully and rapidly in opposite directions. Nrepresents a frame, which is mounted on the axis of the wheels a. andcarries gearing which mesheswth said wheels, the axis of one of thegear-wheels of each side of the frame being squared for the attachmentof a crankhandle, the side pieces of said franiez which form legs, beingmade of removable partsy o r cned and shortened, and the lower endsthereof are pointed, so as to. pierce the iioor or seat 2 5 of theprivy, for securelysustaining the frame and connected parts of thedevice. For pun.

cumstances I employ keepers or eyes P, which may befscrewed tothe risersof the privy-.seat 3o and have thev legs or side pieces of the fram-epass through them, the-wallsy of the keepers be-v ing perforated for thepassage` of the bolts, gf, which connect the lengths of said legs, orside pieces, whereby the legs and keepers. may be 3 5 firmly securedtogether. Where themasswith in the well or cesspool is thick or stiffitis nec.-

essary to cut or break the same. For this purposei I employ cutters Q,which are pivoted toa rod, R, on the under side of the plate- J,A and 4ohave attached to them chains or ropes S, which are-connected to a chainor rope, S, common to.A

a horizontal position, or folded upwardly to an upright position. In thelatter position the cutters may be lowered into the mass,` and when theplate JT is raised the {cutters are brought out to the horizontalposition,` and so present their edges to the mass and cut or breakthrough the same. 5o peated, the cutters being shifted on the-rod- R,

have accomplished their purpose they arefully raised by the chain orrope SQ. and so;

5 5 or seat. In the use of the cutters the bucket is. temporarilyremoved, and reapplied when the mass is in condition to be worked.

The rope or chain Ck is connected with the requires.

The operation is as follows.: The framersL is passed through an opening-in the'l flooror seat of the privy and firmly securedin position by thedevices hereinbefore stated,

its lower end being pointed to take firm hold of the ground. Power isapplied to the spout, (shown in dotted lines, Fig. 1,) arranged `tofbethrcwn up te, permit the passage oi the bucket,l and returning toitsnormal position ywhenit' receives the contents of the bucket.adjustably-connected pieces soas toibe length- 1 the topof the bucketare spurs T, which are Y so disposed that when the bucket rises they 1will catch any articles of clothing, fabrics, &c. Y f that may have beenthrown intoI the well. poses of holding the frame N,under some cir- Y ofthe frame A, I pivot to the inner sides of one section arms U, totheouter end of which are pivoted lugs V, which extend along the sides ofsaid arms, and have curved ends which are adapted to engage with curveddepressions f interlocked by tongues and grooves or keepers, jthetongues projecting from one section and entering the grooves or keepersof the other esection, it beingy seen that by these several provisionsthe sections, when set up, are-firmly connected as one.
